CAR-TRUCK.

Specification of Letters Patent.

Application filed November 4, 1912.

Patented A'iio. 4, 1914:. serial No. 729,314.

To all whom it may concern.'

Be it known that, I, Jixiuiis T. Hanser, of Philadelphia, in the county oi" Philadelphia and State ot' Pennsylvania, have invented certain new and useful Improvements in Car-'lriic-ks, whereof the followingis a specification, reference being had to the accompanying' drawings.`

The invention relates more particularly to a device for facilitating the travel of a car upon curved portions oiE aI track by permitting' and insuring such movements of the wheelsand axles, relative to the car-body, as will tend to minimize undesirable resistance between the wheel flanges and the rails. In my co-pending application, Serial No. 607,290, tiled February 8th, 1911, I have disclosed devices of this general character, wherein the supporting means which intervenes between the car-body and the axles, or trucks, includes pivotal supports located at a lateral distance from the median plane between the wheels carried by each axle, and on opposite sides of said plane, and also includes traveling1 supports located respectively on the free, or non-pivotal sides. This system permits the axles, or trucks, to move relatively to the car-body about substantially definite vert-ical axes 1ocatcd at a distance laterally from said median pian-e, said vertical axes for the respective axles or trucks being on opposite sides ot' said median plane, but in the specitic organization shown and described in ifletuil in said application, it is evident that ai; the pivoted side ot' each truck, the carbody has only a relatively limited support against gravity, namely, directly at or irnmcdiately around the pivotal connection itself.

An object of the present invention is to provide auxiliary supportingmeans which is separate from the pivotal support, but located on the same side of the median plane as the pivotal support, which auxiliary supporting` means prevents any objectionable rocking' movements of the carbody on said pivotal support, without interfering with the rotative movements of the carbody relative to the axle or truck `on said pivotal support.

In the accompanying drawings, which show a convenient embodiment of the invention, Figure I, is a partial side elevation of a car-bcdy provided with trucks of the character referred to. and provided with my iinprovcd intervening supportinrr means between the cai-body and the trucks. Fig. II, is a side elevation of one of the trucks with my improved supportingineans applied thereto. Fig. III, is a side elevation of the opposite side of the truck. Fig. IV, is a detail view, showing, in vertical section, a preferred torni of the pivotal supporting connection, which intervenes between the car-body and the truck. Figi: V, is a top pian view oi. one oit the trucks, also showing a pai-t oit the iunlcrilraiiie of the car.`

The carbody may be oi. any desired construction and includes an undcrt'rame l, which is supported by car trucks 2, and, 3. .lhe construction ot these trucks is similar throughout, the relative positions of certain parts being merely reversed with relation to the sides of the car, and hence it will be only necessary to describe one of them in detail. The truck, inv the embodiment herein shown, is provided with a single axle l, and a pair of wheels 5, The axle is supported in the usual journal boxes, and the organization includes springs and brake mechanism or other adjuncts which it is deemed unnecessary to describe, as these `features are not in any way directly related to the present invention.

Referring more particularly to Figs. II, and 1V, it will be noted that the truck f2, is provided upon the side which is `nearest to the observer, with a hollow bearing G. This bearing; (V5, has a vertical cylindrical opening T, (see Figi'. IV), surrounded by an outwardly projecting annular flange 8, which part may be cast integrally with the rigid side piece 9,015 the truck. Said bearing is adapted to freely receive a vertical supporting' pivot 10, having an annular flange 1l, which bears upon the flange S.

The side beam l2, of the underfraine rests upon a portion of the flange l1, and the latter, with its pivot, is rigidly attached to said beam 12, by means of the upwardly extending face plate 13, which is bolted to the side of the beam.

The axis of the pivotal supporting connection, as will be apparent from Fig. V, is located at a substantial distance laterally from the longitudinal center of the axle.

As a matter of preference in this partcular embodiment, the pivot is arranged, as herein shown, above one extr nity oi said axle and beyond tie outer tace or the car Wheel. This pivotal connection betvveen the carelrody and the truck permits each carbody and truck to swing Vwith relation to one anotlie around a sul'istantially definite vertical z: s located at a di nnce laterally 'from the median piane between the car .vheels. it th side of the iruck opposite to this pivotal connection, (and which may be. termed the free, or non-pivoted side), l have provided a traveling; support which interveues bet-Ween the car-body and the truck and which is adapted to sustiv the car-body at that side ot the truck, while permitting,` a swinging movement of the truck and axle, with relation to the ear-body, about the axis or' said pivotal connection.

Referring more paii'ticiilarly to Figs. lli, and V, it ivill be noted that tivo uprights, 14 and 15, are rigidly mountei upon the side piece ot' the truck, and itriction rollers 16, and 1'?, are iii-ounted to turn freely in said upright supports "'pectively. These rollers are ari'an ed le and along;v

J\f K` tivo tracks, 18, and 1li), ectively, having aces. a shown,

double inclined under and preferably ltornied ot a segmental dat bar secured upon the b om oY the side beam 1i?, olf the undcrtrane, so that the carbody rests at that region upon said `friction rollers. The of said rollers siould be arranged radially ivith relation to the axis of the pivotal support G, upon the opposite side oit the truck. and the segmental tracks 18, and 19, should be concentric with said As before stated, the tivo trucks f2., and 3, are counterparts in. construction; the only difference oit arrangement being that the po* sitions of tie pivotal supporting connection and traveling; supports are reversed with relation to the median plane of the car Wheels. These trucks are connected together by a rigid connecting` link v,c l), ivhic'h extends diagonally across the car-body and is pivotally attach d to tlie trucks respectively at their i ce or non-pivoted sides. This link constitutes a means for correlao ing` the move nents oit the twicks.

The above described parts are fully shown and described in my (1o-pending application above referred to, and further description thereof, and the oper tion ot said devices is not thought lt Will. be apparent from the above description that there are .substantially three points of support between each truck and the car-body; one point being,` at the pivot, and the other two points being at the triction rollers 16, and l?.

While the car-body thus has two points of support relatively to the truck, on one side of the median plane, the above described construction provides only one supporting point on the other side of said median plane. in order to avoid objectionable rocking` movements oit the car-body relative to the truck, or tilting` ot' the truck, on that side of the median plane Where the pivotal support oi the truck is situated, l have provided auviliary supporting` devices, which form a part of the supporting means intervening between the car body and the truck, and

these auxiliary supporting devices operate independently of the pivotal support to secure teir supporting functions, While pernrt ing` the characteristic desired movenientsbi: the car-body relative to the truck about the axis oil the pivotal support.

ln the 'present embodiment of my invention the auxiliary supporting devices comyrise tivo depending' brackets 521, which are didly secured to the side beam, 12, ot' the underiraine ot the car body. rEhe lower ends oft said brackets are projected inward toivard the truck, as indicated at 22, so as to under-luino,` correlative 'upwardly extending through said apertures. The under 'tacos ot',

the projected parts 22, of the brackets 21, are formed with similarly shaped inverted cups or seats 2% having` apertures at the top, which seats respectively receive correspondingly shaped Washers or heads 29, carried at the Yloiver ends of the links 27, which extend through said apertures.

rl`he Washers or heads 26, and 29, are preferably constructed screw nuts, engaging with threaded portions ot the respective eK- iitics of the links, and hence can be adjusted, at the proper position. The faces oi' the brackets proximate to the links, at the regions immediately adjacent to the heads, are cut aivay or holloived, to allow of a free but limited movement ot the links, and the semispherical seats in the brackets provide a ,globe joint, or universal connection between the links and the brackets, which permits sivinningi; movement of the parts in any direction relatively to one another.`

By the above construction, part ot the Weight ot the car-body may at all times be normally carried by the brackets 23, through the links 27, Which connect them with the brackets Q1. l have thus provided three normal. points oi support torthe car-body with relation to the tr ck upon. that sid-e of the 4median plane at.v which the pivotal support is located, one of which points is at or immediately around the pivotal support itself, the other twopoints being at the brackets 21.

As swingingl movement oi the linksl occurs, more et the weight may be transferred thereto, thus relieving, to that extent, the support at or immediately around the pivot itself. liiirtliermore, any objectionable tilting, or rocxing movement ot the trucl-r with relation to the pivot, is obviated, and thus there is no .liability et' binding at the pivot.

.From the above deseription .it will be apvparent that l have provided a supporting means for the car-body intervening between said cari-body and the truck, which includes a pivotal support having a substantially detinite vertical axis located upon one side of the median plane and at a siilbstanlial distance therefrom, and which also includes an auxiliary support independent of the pivotal support and disposed on the same side of the median plane of the car wheels as the pivotal support, and which further includes two traveling' supports upon the opposite side of the median plane, so that there may be Erve points oit' support between the earbody and the truck, whenprunning upon a straight track.

lt is obvious that the terms car and canbody, as used in this description, comin-cheval broadly any wheeled vehicle which is adapted to run upon` a railed track, and that the term truck .is used as coinprehending' broadly any structure adapted to support the body of a car with relation to the axle of the car wheels irrespective ot' whether said truck includes a single axle and a pair of wheels or two axles and four wheels, and also irrespective ot' any pa rticular character or details oit the supporting structure of the truck.

It will be understood 'that in the boardest aspects ol the invention l do not limit 1ny selt to the use ot the specific elements described, nor do l limit myself to the particular arrangement ol parts herein shown.
